【摘 要】 在电力系统中，36v以下的电压称为安全电压，1kv以下的电压称为低压，1kv以上的电压称为高压，直接供电给用户的线路称为配电线路，如用户电压为380/220v，则称为低压配电线路，也就是家庭装修中所说的强电。强电一般是指交流电电压在24V以上，如生活中常用的照明灯具、电热水器、取暖器、冰箱、电视机、音响设备等均为强电电气设备。反之弱电一般则指直流电路或音频、视频线路、网络线路、电话线路，直流电压在24V以内者。

    [Abstract] in the power system, 36v voltage below the voltage referred to as security, 1kv the following operating voltages, 1kv more as high voltage direct supply lines to the user known as distribution lines, such as user voltage 380/220v, is called low-voltage distribution lines, that is, the family said in a strong electric decoration. Strong power generally refers to more than 24V AC voltage, such as commonly used in life lighting, electric water heaters, heaters, refrigerators, televisions, audio equipment and other electrical equipment are the strong power. Weak hand refers to the DC circuit or general audio, video lines, Internet lines, telephone lines, those less than 24V DC voltage.
